However, instructors often find it difficult to assess the quality of online group dynamics without visual observations of student behaviors. The purpose of this study was to investigate the use of…

This paper presents a characterization of computer-based interactions by which learners can explore and investigate visual mathematical representations (VMRs). VMRs (e.g., geometric structures, graphs, and diagrams) refer to graphical representations that visually encode properties and relationships of mathematical structures and concepts.…

This paper presents and evaluates a new procedure to classify examinees into meaningful categories based on their responses to (performance on) items comprising a test instrument. The proposed procedure uses the data analytic technique of cluster analysis to partition the examinee population into homogeneous groupings. This procedure was applied…

This book articulates and defends the "theory theory" of cognitive and semantic development: the idea that very young children just beginning to talk are engaged in profound restructurings of several domains of their knowledge.
